Cover for nano tank

[Steve-O-]

Man i can't stop making posts hehe, well here is today's thing i have my 10g nano open topped due to i have my MH 150 over it hanging. Ok lol now here is the thing why i need a cover.
I had a black and white damsel (( i didn't know they jumped )) when i woke up in the morning and looked in the tank he was gone." hmmm" i said "where the hell is he". I scanned the rocks and sand he wasn't anywhere to be found, then i looked around the tank still not there.
So i was like "oh well" i went to grab my cheap sal meter and guess who was dead inside lol talk about shot of a lifetime my god.........

So should i get some acylic and make a top with holes in the middle?? or is it back to cover small tanks since i can't have a hood due to my lights.

BTW sorry about my messy writing hehe not to good at it.
